Description

The present invention relates to a method of constructing a C-shaped steel material for roofing and a fixing device.

Therefore, as a result of investigating known techniques for fixing methods and means for fixing roof body metal fittings, which are called C-shaped steel materials in the industry, without using screws, the following documents are listed. Was present.

Japanese Unexamined Patent Publication No. 9-324501 Japanese Unexamined Patent Publication No. 2-279894 Jitsukaisho 64-33803

However, the techniques disclosed in each of these publications have the following contents. That is,

In Patent Document 1, the tightening portions of both C-type steel materials facing each other and overlapped are inserted into the C-type steel material mounting portion, and the bolts attached to the C-type steel material tightening portions are rotated to tighten the C-type steel material. Although it is disclosed that the portion moves and that the C-shaped steel tightening portion has an insertion portion into which the collar portion of the C-type steel material can be inserted, the clip portion of the C-type steel material is provided in the C-type steel material mounting portion. The groove to be inserted is not disclosed. (See Fig. 2, Fig. 3, Fig. 5, and Fig. 6 in the publication)

Patent Document 2 describes a support member for C-shaped steel that supports the C-shaped steel material, and a pressing member that pushes the outer surface portion of the vertical wall of the C-shaped steel material to slide the C-shaped steel material and lock it to the first locking portion. Although a rotating member having a second locking portion that locks the C-shaped steel by rotating is disclosed, there is no disclosure of a slide metal fitting. (See Fig. 4 in the publication)

Patent Document 3 provides an engaging groove in which one clip portion of one C-shaped cross beam member of the left and right side plates of the mounting bracket is fitted, and by pressing the other clip portion of the C-shaped cross beam member is elastic. Although it is disclosed that it engages with the locking piece, there is no disclosure of the slide fitting. (See FIGS. 5 and 6 in the publication)

Therefore, an object of the present invention is to provide a method and an apparatus for easily and surely fixing a long C-shaped steel material to a main body metal fitting without using screws or the like.

The present invention has a base material having recessed grooves provided on both left and right sides of the C-shaped steel material in the front and rear portions, and an interior material fitted and installed inside the base base material, and one of the C-shaped steel materials. After inserting the clip of the above into one concave groove of the base material, the other clip of the C-shaped steel material is rotated to the opposite side to be inserted and fitted into the other concave groove of the base material and the interior material. The horizontal part of the C-shaped steel material is held parallel to the base material integrated with the interior material, whereby the base material and the C-shaped steel material on the interior material slide appropriately to slide the left and right inner plate parts of the interior material. It is a method of constructing a C-shaped steel material for roofing, and a fixing device, which is formed by engaging and attaching a projecting piece provided on an outer plate portion of the base material to an opening provided in.

In the conventional construction method, after installing the re-roofing metal fittings on the old roofing material, it is common and time-consuming to fix the C-shaped steel material to the top surface of the metal fittings with screws. In the construction method, the mounting work can be performed reliably and easily simply by rotating and sliding when mounting the C-shaped steel material, which saves the labor of the mounting work and eliminates the need for materials such as screws. It is.

In addition, compared to the conventional method that required screwing one by one, the method of the present invention allows it to be attached to the re-roofing metal fittings within that length at once according to the length of the C-shaped steel material. Therefore, it is possible to provide an epoch-making method and means, and even if the shape of the C-shaped steel material itself is deformed, its action and effect do not change.
